The system of equations graphed below has how many solutions? y= 2x+2, y=2x

2 answers:

8 0

Y = 2x + 2
Y = 2x -
Subtract

0 = 2

This makes no sense meaning the lines are parallel. Therefore there are 0 solutions.

0 solutions. Using the slope-intercept form y=mx+b, you can tell that the slope m for both lines is 2. Two lines that have the same slope are parallel. Since they are parallel, they don't intersect, hence there are no solutions to the system.

Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage r

svetlana [45]

Answer:

For any exponential function in which the base is less than 1, it will be an exponential decay situation. In this problem, the base is 0.97. The amount that the base is less than 1 ( i.e. 1 - base) represents, in decimal form, the percent of decrease, which in this case is 0.03 or 3%.

Step-by-step explanation:

The formula for exponential decay is y=a(1-r)x.

r is the decay rate.

So,

To find the median, arrange all the numbers from least to greatest.

10, 31, 36, 36, 38, 42, 47, 48, 49, 52

The middle two numbers are 38 and 42. Take their average.
40

40 is the median of 10, 31, 36, 36, 38, 42, 47, 48, 49, and 52.

Tom Worker pays $900 annually for $60,000 worth of life insurance.

Amanda [17]

Answer: 1) $9000

2) $5340

3)59.3%

Step-by-step explanation:

Since we have given that

Worth of life insurance = $60000

Amount of premium = $900

After the end of 10 years,

1) Amount of premium Tom had paid is given by

$10\times 900=\$9000$

2) At the end of 10 years ,

The cash value of his policy by using the table is given by

$\frac{89}{1000}\times 60000\\\\=\$5340$

3) At the end of 10 years ,

Ratio of cash value to premiums paid be

$5340:9000\\\\=\frac{5340}{9000}\times 100\\\\=59.3\%$
